One of America's most famous criminals, Jesse James, is shot to death by fellow gang member Bob Ford, who betrayed James for reward money. For 16 years, Jesse and his brother, Frank, committed robberies and murders throughout the Midwest. Detective magazines and pulp novels glamorized the James gang, turning them into mythical Robin Hoods who were driven to crime by unethical landowners and bankers. In reality, Jesse James was a ruthless killer who stole only for himself.

The teenage James brothers joined up with southern guerrilla leaders when the Civil War broke out. Both participated in massacres of settlers and troops affiliated with the North. After the war was over, the quiet farming life of the James brothers' youth no longer seemed enticing, and the two turned to crime. Jesse's first bank robbery occurred on February 13, 1866, in Liberty, Missouri.

Over the next couple of years, the James brothers became the suspects in several bank robberies throughout western Missouri. However, locals were sympathetic to ex-southern guerrillas and vouched for the brothers. Throughout the late 1860s and early 1870s, the James gang robbed only a couple banks a year, otherwise keeping a low profile.

In 1873, the James gang got into the train robbery game. During one such robbery, the gang declined to take any money or valuables from southerners. The train robberies brought out the Pinkerton Detective Agency, employed to bring the James gang to justice. However, the Pinkerton operatives' botched attempt to kill James left a woman and her child injured and elicited public sympathy for Jesse and Frank James.

The James gang suffered a setback in 1876 when they raided the town of Northfield, Minnesota. The Younger brothers, cousins of the James brothers, were shot and wounded during the brazen midday robbery. After running off in a different direction from Jesse and Frank, the Younger brothers were captured by a large posse and later sentenced to life in prison. Jesse and Frank, the only members of the gang to escape successfully, headed to Tennessee to hide out.

After spending a few quiet years farming, Jesse organized a new gang. Charlie and Robert Ford were on the fringe of the new gang, but they disliked Jesse intensely and decided to kill him for the reward money. On April 3, while Jesse's mother made breakfast, the new gang met to hear Jesse's plan for the next robbery. When Jesse turned his back to adjust a picture on the wall, Bob Ford shot him several times in the back.

His tombstone reads, "Jesse W. James, Died April 3, 1882, Aged 34 years, 6 months, 28 days, Murdered by a traitor and a coward whose name is not worthy to appear here."

"The Assassination of Jesse James by the Coward Robert Ford" depicts this brilliantly.

Just after 6 p.m. on April 4, 1968, Martin Luther King Jr. is fatally shot while standing on the balcony outside his second-story room at the Lorraine Motel in Memphis, Tennessee. The civil rights leader was in Memphis to support a sanitation workers' strike and was on his way to dinner when a bullet struck him in the jaw and severed his spinal cord. King was pronounced dead after his arrival at a Memphis hospital. He was 39 years old.

In the months before his assassination, Martin Luther King became increasingly concerned with the problem of economic inequality in America. He organized a Poor People's Campaign to focus on the issue, including an interracial poor people's march on Washington, and in March 1968 traveled to Memphis in support of poorly treated African-American sanitation workers. On March 28, a workers' protest march led by King ended in violence and the death of an African-American teenager. King left the city but vowed to return in early April to lead another demonstration.

On April 3, back in Memphis, King gave his last sermon, saying, "We've got some difficult days ahead. But it really doesn't matter with me now, because I've been to the mountaintop...And He's allowed me to go up to the mountain. And I've looked over, and I've seen the Promised Land. I may not get there with you. But I want you to know tonight that we, as a people, will get to the promised land."

One day after speaking those words, Dr. King was shot and killed by a sniper. As word of the assassination spread, riots broke out in cities all across the United States and National Guard troops were deployed in Memphis and Washington, D.C. On April 9, King was laid to rest in his hometown of Atlanta, Georgia. Tens of thousands of people lined the streets to pay tribute to King's casket as it passed by in a wooden farm cart drawn by two mules.

The evening of King's murder, a Remington .30-06 hunting rifle was found on the sidewalk beside a rooming house one block from the Lorraine Motel. During the next several weeks, the rifle, eyewitness reports, and fingerprints on the weapon all implicated a single suspect: escaped convict James Earl Ray. A two-bit criminal, Ray escaped a Missouri prison in April 1967 while serving a sentence for a holdup. In May 1968, a massive manhunt for Ray began. The FBI eventually determined that he had obtained a Canadian passport under a false identity, which at the time was relatively easy.

On June 8, Scotland Yard investigators arrested Ray at a London airport. He was trying to fly to Belgium, with the eventual goal, he later admitted, of reaching Rhodesia. Rhodesia, now called Zimbabwe, was at the time ruled by an oppressive and internationally condemned white minority government. Extradited to the United States, Ray stood before a Memphis judge in March 1969 and pleaded guilty to King's murder in order to avoid the electric chair. He was sentenced to 99 years in prison.

Three days later, he attempted to withdraw his guilty plea, claiming he was innocent of King's assassination and had been set up as a patsy in a larger conspiracy. He claimed that in 1967, a mysterious man named "Raoul" had approached him and recruited him into a gunrunning enterprise. On April 4, 1968, he said, he realized that he was to be the fall guy for the King assassination and fled to Canada. Ray's motion was denied, as were his dozens of other requests for a trial during the next 29 years.

During the 1990s, the widow and children of Martin Luther King Jr. spoke publicly in support of Ray and his claims, calling him innocent and speculating about an assassination conspiracy involving the U.S. government and military. U.S. authorities were, in conspiracists' minds, implicated circumstantially. FBI Director J. Edgar Hoover obsessed over King, who he thought was under communist influence. For the last six years of his life, King underwent constant wiretapping and harassment by the FBI. Before his death, Dr. King was also monitored by U.S. military intelligence, which may have been asked to watch King after he publicly denounced the Vietnam War in 1967. Furthermore, by calling for radical economic reforms in 1968, including guaranteed annual incomes for all, King was making few new friends in the Cold War-era U.S. government.

Over the years, the assassination has been reexamined by the House Select Committee on Assassinations, the Shelby County, Tennessee, district attorney's office, and three times by the U.S. Justice Department. The investigations all ended with the same conclusion: James Earl Ray killed Martin Luther King. The House committee acknowledged that a low-level conspiracy might have existed, involving one or more accomplices to Ray, but uncovered no evidence to definitively prove this theory. In addition to the mountain of evidence against him--such as his fingerprints on the murder weapon and his admitted presence at the rooming house on April 4--Ray had a definite motive in assassinating King: hatred. According to his family and friends, he was an outspoken racist who informed them of his intent to kill Dr. Martin Luther King, Jr. He died in 1998.

Modern rock icon Kurt Cobain commits suicide on this day in 1994. His body was discovered inside his home in Seattle, Washington, three days later by Gary Smith, an electrician, who was installing a security system in the suburban house. Despite indications that Cobain, the lead singer of Nirvana, killed himself, several skeptics questioned the circumstances of his death and pinned responsibility on his wife, Courtney Love.

At least two books, including one penned by Love's estranged father, and a nationally released documentary, Kurt & Courtney, openly expressed doubt that Cobain killed himself and all but accused Love of having her husband killed. Her volatile reputation and healthy list of enemies helped to circulate the rumors. However, police have concluded that Cobain's death was the result of suicide.

Cobain's downward spiral began taking shape in Italy the previous month. He went into a coma and nearly died after mixing champagne and the drug Rohypnol. The public was led to believe that the coma was induced by an accidental heroin overdose, since Cobain had a well-known problem with the drug.

Back at home in Seattle, the police were called to Cobain and Love's home when he again threatened to kill himself. Although Cobain stated in a 1991 interview that he didn't believe in guns, the officers confiscated four from his possession. As his wife and friends watched him spin out of control, they attempted to intervene. Cobain mostly ignored their concerns but reluctantly checked into a rehabilitation clinic in Los Angeles at the end of March.

On March 30, Cobain walked away from the clinic without informing his family or friends. For the next few days, Love could not locate him and decided to hire a private detective on April 3. The detective made contact with Cobain the following day in Seattle, but Cobain refused to return to Los Angeles.

In the meantime, Cobain had convinced a friend to buy him a gun, claiming he needed it for protection. On April 5, Cobain returned home. He had ingested enough Valium and heroin to reach near-fatal levels. In the apartment above the garage was Cobain's sloppily written suicide note, quoting Neil Young's lyric that it is "better to burn out than to fade away."

In Fayette Township, New York, Joseph Smith, founder of the Mormon religion, organizes the Church of Christ during a meeting with a small group of believers.

Born in Vermont in 1805, Smith claimed in 1823 that he had been visited by a Christian angel named Moroni who spoke to him of an ancient Hebrew text that had been lost for 1,500 years. The holy text, supposedly engraved on gold plates by a Native American historian in the fourth century, related the story of Israelite peoples who had lived in America in ancient times. During the next six years, Smith dictated an English translation of this text to his wife and other scribes, and in 1830 The Book of Mormon was published. In the same year, Smith founded the Church of Christ--later known as the Church of Jesus Christ of Latter-day Saints--in Fayette Township.

The religion rapidly gained converts, and Smith set up Mormon communities in Ohio, Missouri, and Illinois. However, the Christian sect was also heavily criticized for its unorthodox practices, such as polygamy, and on June 27, 1844, Smith and his brother were murdered in a jail cell by an anti-Mormon mob in Carthage, Illinois.

Two years later, Smith's successor, Brigham Young, led an exodus of persecuted Mormons from Nauvoo, Illinois, along the western wagon trails in search of religious and political freedom. In July 1847, the 148 initial Mormon pioneers reached Utah's Valley of the Great Salt Lake. Upon viewing the valley, Young declared, "This is the place," and the pioneers began preparations for the tens of thousands of Mormon migrants who would follow them and settle there.

On this day in 1994, Rwandan armed forces kill 10 Belgian peacekeeping officers in a successful effort to discourage international intervention in the genocide that had begun only hours earlier. In approximately three months, the Hutu extremists who controlled Rwanda brutally murdered an estimated 500,000 to 1 million innocent civilian Tutsis and moderate Hutus in the worst episode of ethnic genocide since World War II.

The immediate roots of the 1994 genocide dated back to the early 1990s, when President Juvenal Habyarimana, a Hutu, began using anti-Tutsi rhetoric to consolidate his power among the Hutus. Beginning in October 1990, there were several massacres of hundreds of Tutsis. Although the two ethnic groups were very similar, sharing the same language and culture for centuries, the law required registration based on ethnicity. The government and army began to assemble the Interahamwe (meaning "those who attack together") and prepared for the elimination of the Tutsis by arming Hutus with guns and machetes. In January 1994, the United Nations forces in Rwanda warned that larger massacres were imminent.

On April 6, 1994, President Habyarimana was killed when his plane was shot down. It is not known if the attack was carried out by the Rwandan Patriotic Front (RPF), a Tutsi military organization stationed outside the country at the time, or by Hutu extremists trying to instigate a mass killing. In any event, Hutu extremists in the military, led by Colonel Theoneste Bagosora, immediately went into action, murdering Tutsis and moderate Hutus within hours of the crash.

The Belgian peacekeepers were killed the next day, a key factor in the withdrawal of U.N. forces from Rwanda. Soon afterward, the radio stations in Rwanda were broadcasting appeals to the Hutu majority to kill all Tutsis in the country. The army and the national police directed the slaughter, sometimes threatening Hutu civilians when persuasion didn't work. Thousands of innocent people were hacked to death with machetes by their neighbors. Despite the horrific crimes, the international community, including the United States, hesitated to take any action. They wrongly ascribed the genocide to chaos amid tribal war. President Bill Clinton later called America's failure to do anything to stop the genocide "the biggest regret" of his administration.

It was left to the RPF, led by Paul Kagame, to begin an ultimately successful military campaign for control of Rwanda. By the summer, the RPF had defeated the Hutu forces and driven them out of the country and into several neighboring nations. However, by that time, an estimated 75 percent of the Tutsis living in Rwanda had been murdered.

On this day, Buddhists celebrate the commemoration of the birth of Gautama Buddha, the founder of Buddhism, thought to have lived in India from 563 B.C. to 483 B.C. Actually, the Buddhist tradition that celebrates his birthday on April 8 originally placed his birth in the 11th century B.C., and it was not until the modern era that scholars determined that he was more likely born in the sixth century B.C., and possibly in May rather than April.

According to the Tripitaka, which is recognized by scholars as the earliest existing record of the Buddha's life and discourses, Gautama Buddha was born as Prince Siddhartha, the son of the king of the Sakya people. The kingdom of the Sakyas was situated on the borders of present-day Nepal and India. Siddhartha's family was of the Gautama clan. His mother, Queen Mahamaya, gave birth to him in the park of Lumbini, in what is now southern Nepal. A pillar placed there in commemoration of the event by an Indian emperor in the third century B.C. still stands.

At his birth, it was predicted that the prince would either become a great world monarch or a Buddha--a supremely enlightened teacher. The Brahmans told his father, King Suddhodana, that Siddhartha would become a ruler if he were kept isolated from the outside world. The king took pains to shelter his son from misery and anything else that might influence him toward the religious life. Siddhartha was brought up in great luxury, and he married and fathered a son. At age 29, he decided to see more of the world and began excursions off the palace grounds in his chariot. In successive trips, he saw an old man, a sick man, and a corpse, and since he had been protected from the miseries of aging, sickness, and death, his charioteer had to explain what they were. Finally, Siddhartha saw a monk, and, impressed with the man's peaceful demeanor, he decided to go into the world to discover how the man could be so serene in the midst of such suffering.

Siddhartha secretly left the palace and became a wandering ascetic. He traveled south, where the centers of learning were, and studied meditation under the teachers Alara Kalama and Udraka Ramaputra. He soon mastered their systems, reaching high states of mystical realization, but was unsatisfied and went out again in search of nirvana, the highest level of enlightenment. For nearly six years, he undertook fasting and other austerities, but these techniques proved ineffectual and he abandoned them. After regaining his strength, he seated himself under a pipal tree at what is now Bodh Gaya in west-central India and promised not to rise until he had attained the supreme enlightenment. After fighting off Mara, an evil spirit who tempted him with worldly comforts and desires, Siddhartha reached enlightenment, becoming a Buddha at the age of 35.

The Gautama Buddha then traveled to the deer park near Benares, India, where he gave his first sermon and outlined the basic doctrines of Buddhism. According to Buddhism, there are "four noble truths": (1) existence is suffering; (2) this suffering is caused by human craving; (3) there is a cessation of the suffering, which is nirvana; and (4) nirvana can be achieved, in this or future lives, though the "eightfold path" of right views, right resolve, right speech, right action, right livelihood, right effort, right mindfulness, and right concentration.

For the rest of his life, the Buddha taught and gathered disciples to his sangha, or community of monks. He died at age 80, telling his monks to continue working for their spiritual liberation by following his teachings. Buddhism eventually spread from India to Central and Southeast Asia, China, Korea, Japan, and, in the 20th century, to the West. Today, there are an estimated 350 million people in 100 nations who adhere to Buddhist beliefs and practices.

At Appomattox, Virginia, Confederate General Robert E. Lee surrenders his 28,000 troops to Union General Ulysses S. Grant, effectively ending the American Civil War. Forced to abandon the Confederate capital of Richmond, blocked from joining the surviving Confederate force in North Carolina, and harassed constantly by Union cavalry, Lee had no other option.

In retreating from the Union army's Appomattox Campaign, the Army of Northern Virginia had stumbled through the Virginia countryside stripped of food and supplies. At one point, Union cavalry forces under General Philip Sheridan had actually outrun Lee's army, blocking their retreat and taking 6,000 prisoners at Sayler's Creek. Desertions were mounting daily, and by April 8 the Confederates were surrounded with no possibility of escape. On April 9, Lee sent a message to Grant announcing his willingness to surrender. The two generals met in the parlor of the Wilmer McLean home at one o'clock in the afternoon.

Lee and Grant, both holding the highest rank in their respective armies, had known each other slightly during the Mexican War and exchanged awkward personal inquiries. Characteristically, Grant arrived in his muddy field uniform while Lee had turned out in full dress attire, complete with sash and sword. Lee asked for the terms, and Grant hurriedly wrote them out. All officers and men were to be pardoned, and they would be sent home with their private property--most important, the horses, which could be used for a late spring planting. Officers would keep their side arms, and Lee's starving men would be given Union rations.

Shushing a band that had begun to play in celebration, General Grant told his officers, "The war is over. The Rebels are our countrymen again." Although scattered resistance continued for several weeks, for all practical purposes the Civil War had come to an end.

On April 10, 1866, the American Society for the Prevention of Cruelty to Animals (ASPCA) is founded in New York City by philanthropist and diplomat Henry Bergh, 54.

In 1863, Bergh had been appointed by President Abraham Lincoln to a diplomatic post at the Russian court of Czar Alexander II. It was there that he was horrified to witness work horses beaten by their peasant drivers. En route back to America, a June 1865 visit to the Royal Society for the Prevention of Cruelty to Animals in London awakened his determination to secure a charter not only to incorporate the ASPCA but to exercise the power to arrest and prosecute violators of the law.

Back in New York, Bergh pleaded on behalf of "these mute servants of mankind" at a February 8, 1866, meeting at Clinton Hall. He argued that protecting animals was an issue that crossed party lines and class boundaries. "This is a matter purely of conscience; it has no perplexing side issues," he said. "It is a moral question in all its aspects." The speech prompted a number of dignitaries to sign his "Declaration of the Rights of Animals."

Bergh's impassioned accounts of the horrors inflicted on animals convinced the New York State legislature to pass the charter incorporating the ASPCA on April 10, 1866. Nine days later, the first effective anti-cruelty law in the United States was passed, allowing the ASPCA to investigate complaints of animal cruelty and to make arrests.

Bergh was a hands-on reformer, becoming a familiar sight on the streets and in the courtrooms of New York. He regularly inspected slaughter houses, worked with police to close down dog- and rat-fighting pits and lectured in schools and to adult societies. In 1867, the ASPCA established and operated the nation's first ambulance for horses.

As the pioneer and innovator of the humane movement, the ASPCA quickly became the model for more than 25 other humane organizations in the United States and Canada. And by the time Bergh died in 1888, 37 of the 38 states in the Union had passed anti-cruelty laws.

Bergh’s dramatic street rescues of mistreated horses and livestock served as a model for those trying to protect abused children. After Mary Ellen McCormack, 9, was found tied to a bed and brutally beaten by her foster parents in 1874, activists founded the New York Society for the Prevention of Cruelty to Children. Bergh served as one of the group’s first vice presidents.

On this day in 1814, Napoleon Bonaparte, emperor of France and one of the greatest military leaders in history, abdicates the throne, and, in the Treaty of Fontainebleau, is banished to the Mediterranean island of Elba.

The future emperor was born in Ajaccio, Corsica, on August 15, 1769. After attending military school, he fought during the French Revolution of 1789 and rapidly rose through the military ranks, leading French troops in a number of successful campaigns throughout Europe in the late 1700s. By 1799, he had established himself at the top of a military dictatorship. In 1804, he became emperor of France and continued to consolidate power through his military campaigns, so that by 1810 much of Europe came under his rule. Although Napoleon developed a reputation for being power-hungry and insecure, he is also credited with enacting a series of important political and social reforms that had a lasting impact on European society, including judiciary systems, constitutions, voting rights for all men and the end of feudalism. Additionally, he supported education, science and literature. His Code Napoleon, which codified key freedoms gained during the French Revolution, such as religious tolerance, remains the foundation of French civil law.

In 1812, thinking that Russia was plotting an alliance with England, Napoleon launched an invasion against the Russians that eventually ended with his troops retreating from Moscow and much of Europe uniting against him. In 1814, Napoleon's broken forces gave up and Napoleon offered to step down in favor of his son. When this offer was rejected, he abdicated and was sent to Elba. In March 1815, he escaped his island exile and returned to Paris, where he regained supporters and reclaimed his emperor title, Napoleon I, in a period known as the Hundred Days. However, in June 1815, he was defeated at the bloody Battle of Waterloo. Napoleon's defeat ultimately signaled the end of France's domination of Europe. He abdicated for a second time and was exiled to the remote island of Saint Helena, in the southern Atlantic Ocean, where he lived out the rest of his days. He died at age 52 on May 5, 1821, possibly from stomach cancer, although some theories contend he was poisoned.

While on a vacation in Warm Springs, Georgia, President Roosevelt suffers a stroke and dies. His death marked a critical turning point in U.S. relations with the Soviet Union, as his successor, Harry S. Truman, decided to take a tougher stance with the Russians.

By April 1945, Roosevelt had been elected president of the United States four times and had served for over 12 years. He had seen the United States through some of its darkest days, from the depths of the Great Depression through the toughest times of World War II. In early 1945, shortly after being sworn in for his fourth term as president, Roosevelt was on the verge of leading his nation to triumph in the Second World War. Germany teetered on the brink of defeat, and the Japanese empire was crumbling under the blows of the American military. In February 1945, Roosevelt traveled to Yalta in the Soviet Union to meet with Russian leader Joseph Stalin and British Prime Minister Winston Churchill to discuss the postwar world. Roosevelt returned from these intense meetings drawn and sick. He vacationed in Warm Springs, Georgia, but the rest did not lead to recuperation. On April 12, 1945, he suffered a massive stroke and died.

Roosevelt left a controversial legacy in terms of U.S.-Soviet relations. Critics charged that the president had been "soft" on the communists and naive in dealing with Stalin. The meetings at Yalta, they claimed, resulted in a "sellout" that left the Soviets in control of Eastern Europe and half of Germany. Roosevelt's defenders responded that he made the best of difficult circumstances. He kept the Grand Alliance between the United States, the Soviet Union, and Great Britain intact long enough to defeat Germany. As for Eastern Europe and Germany, there was little Roosevelt could have done, since the Red Army occupied those areas. Roosevelt's successor, Harry S. Truman, decided that a "tougher" policy toward the Soviets was in order, and he began to press the Russians on a number of issues. By 1947, relations between the two former allies had nearly reached the breaking point and the Cold War was in full swing.

On this day in 1997, 21-year-old Tiger Woods wins the prestigious Masters Tournament by a record 12 strokes in Augusta, Georgia. It was Woods' first victory in one of golf's four major championships–the U.S. Open, the British Open, the PGA Championship, and the Masters–and the greatest performance by a professional golfer in more than a century.

Eldrick "Tiger" Woods was born in a suburb of Los Angeles, California, on December 30, 1975. The only child of an African-American father and a Thai mother, Woods was encouraged from infancy by his father for a career in golf. At the age of two, he teed off against comedian Bob Hope on television's Mike Douglas Show. At five years old, he was featured on the television show That's Incredible. At age eight, Tiger won his first junior world championship, and in 1991, at age 15, he became the youngest player ever to win the U.S. Junior Amateur Championship. He also captured the 1992 and 1993 Junior Amateur titles, and in 1994 accepted a scholarship to attend Stanford University. That year, he came from six holes behind to win the first of his three consecutive U.S. Amateur championships. He was 18 years old and the youngest Amateur champion in history.

In 1995, Tiger played the Masters, his first professional major championship. The Augusta National Golf Club, which runs the Masters, had not let an African-American join its ranks until 1991. Woods finished 41st in his first Masters appearance. In 1996, he won the collegiate title. By this time, he was already attracting considerable media attention and attracting throngs of new fans to the sport. After claiming his third U.S. Amateur title, Woods left college and turned professional in August 1996. Playing as a pro in eight Professional Golfers' Association (PGA) events in 1996, he won a title and was named the PGA Tour's outstanding rookie. In December 1996, he was celebrated by the magazine Sports Illustrated as its "Sportsman of the Year."

In professional play, most of Woods' opponents were in their late 30s or early 40s. At 6'2" and 155 pounds, he was slender and athletic, and had developed a devastating swing that routinely allowed him to hit drives of more than 300 yards. He also had a reputation for mental toughness and was a superb putter and chipper. In April 1997, all these attributes came together for the most decisive victory in the Masters' 44-year history.

His margin of victory–12 strokes–was the largest in the 20th century, and second only to Old Tom Morris' 13-shot margin at the 1862 British Open. His score of 18-under-par 270 broke Jack Nicklaus' 32-year-old Masters record of 17-under-par 271. He was the youngest golfer by two years to win the Masters and the first person of Asian or African heritage to win a major. Never before had so many spectators come to Augusta National, and never before had so many people watched it on television.

By June 1997, Tiger was ranked number one in the world. In 1999, he won eight PGA tournaments, earned a record $6 million, and began a winning streak that eventually tied Ben Hogan's 1948 streak, the second longest in PGA history. In June 2000, he won his first U.S. Open title, shooting a record 12-under-par 272 to finish 15 strokes ahead of his nearest competitors. It was the greatest professional golf performance in history, surpassing even his 1997 Masters' triumph and Old Tom Morris' 1862 showing. In July 2000, he captured the British Open, and in August the PGA championship. At the age of 24, he was the youngest player ever to win all four major golf titles and just the second to win three majors in a year. On April 10, 2005, he earned his fourth green sport coat at Augusta National, becoming the first person to win four Masters before age 30.

Tiger’s winning pace slowed around 2004, when he devoted time to reworking his swing and rehabilitating his surgically repaired knee. It was also during this period that he married Elin Nordegren, a Swedish former model who would become the mother of his two children. Tiger was back in top form by 2005, winning his 10th major. His performance fluctuated throughout the rest of the decade as he struggled with a torn ACL and personal problems that garnered substantial media attention: In late 2009, in the wake of events surrounding a car accident outside Tiger’s Florida home, several women came forward claiming to have had affairs with the famous golfer. Nordegren divorced him in August 2010, just as Tiger began his first winless season in his career.

President Abraham Lincoln is shot in the head at Ford's Theatre in Washington, D.C. The assassin, actor John Wilkes Booth, shouted, "Sic semper tyrannis! (Ever thus to tyrants!) The South is avenged," as he jumped onto the stage and fled on horseback. Lincoln died the next morning.

Booth was a well-regarded actor who was particularly loved in the South before the Civil War. During the war, he stayed in the North and became increasingly bitter when audiences weren't as enamored of him as they were in Dixie. Along with friends Samuel Arnold, Michael O'Laughlin, and John Surratt, Booth conspired to kidnap Lincoln and deliver him to the South.

On March 17, along with George Atzerodt, David Herold, and Lewis Paine, the group met in a Washington bar to plot the abduction of the president three days later. However, when the president changed his plans, the scheme was scuttled. Shortly afterward, the South surrendered to the Union and the conspirators altered their plan. They decided to kill Lincoln, Vice President Andrew Johnson, and Secretary of State William Seward on the same evening.

When April 14 came around, Atzerodt backed out of his part to kill Johnson. Upset, Booth went to drink at a saloon near Ford's Theatre. At about 10 p.m. he walked into the theater and up to the president's box. Lincoln's guard, John Parker, was not there because he had gotten bored with the play, Our American Cousin, and left his post to get a beer. Booth easily slipped in and shot the president in the back of the head. The president's friend, Major Rathbone, attempted to grab Booth but was slashed by Booth's knife. Booth injured his leg badly when he jumped to the stage to escape, but he managed to hobble outside to his horse.

Meanwhile, Lewis Paine forced his way into William Seward's house and stabbed the secretary of state several times before fleeing. Booth rode to Virginia with David Herold and stopped at the home of Dr. Samuel Mudd, who placed splints on Booth's legs. They hid in a barn on Richard Garrett's farm as thousands of Union troops combed the area looking for them. The other conspirators were captured, except for John Surratt, who fled to Canada.

When the troops finally caught up with Booth and Herold on April 26, they gave them the option of surrendering before the barn was burned down. Herold decided to surrender, but Booth remained in the barn as it went up in flames. Booth was then shot and killed in the burning barn by Corporal Boston Corbett. On July 7, George Atzerodt, Lewis Paine, David Herold, and John Surratt's mother, Mary, were hanged in Washington. The execution of Mary Surratt is believed by some to have been a miscarriage of justice. Although there was proof of Surratt’s involvement in the original abduction conspiracy,it is clear that her deeds were minor compared to those of the others who were executed.

Her son John was eventually tracked down in Egypt and brought back to trial, but he managed, with the help of clever lawyers, to win an acquittal.

President Abraham Lincoln, the 16th president of the United States, dies from an assassin’s bullet. Shot by John Wilkes Booth at Ford’s Theater in Washington the night before, Lincoln lived for nine hours before succumbing to the severe head wound he sustained.

Lincoln’s death came just after the surrender of Confederate General Robert E. Lee’s army at Appomattox Court House, Virginia. Lincoln had just served the most difficult presidency in history, successfully leading the country through civil war. His job was exhausting and overwhelming at times. He had to manage a tremendous military effort, deal with diverse opinions in his own Republican party, counter his Democratic critics, maintain morale on the northern home front, and keep foreign countries such as France and Great Britain from recognizing the Confederacy. He did all of this, and changed American history when he issued the Emancipation Proclamation, converting the war goal from reunion of the nation to a crusade to end slavery.

Now, the great man was dead. Secretary of War Edwin Stanton said, “Now, he belongs to the ages.” Word spread quickly across the nation, stunning a people who were still celebrating the Union victory. Troops in the field wept, as did General Ulysses S. Grant, the overall Union commander. Perhaps no group was more grief stricken than the freed slaves. Although abolitionists considered Lincoln slow in moving against slavery, many freedmen saw “Father Abraham” as their savior. They faced an uncertain world, and now had lost their most powerful proponent.

Lincoln’s funeral was held on April 19, before a funeral train carried his body back to his hometown of Springfield, Illinois. During the two-week journey, hundreds of thousands gathered along the railroad tracks to pay their respects, and the casket was unloaded for public viewing at several stops. He and his son, Willie, who died in the White House of typhoid fever in 1862, were interred on May 4.

In Basel, Switzerland, Albert Hoffman, a Swiss chemist working at the Sandoz pharmaceutical research laboratory, accidentally consumes LSD-25, a synthetic drug he had created in 1938 as part of his research into the medicinal value of lysergic acid compounds. After taking the drug, formally known as lysergic acid diethylamide, Dr. Hoffman was disturbed by unusual sensations and hallucinations. In his notes, he related the experience:

"Last Friday, April 16, 1943, I was forced to interrupt my work in the laboratory in the middle of the afternoon and proceed home, being affected by a remarkable restlessness, combined with a slight dizziness. At home I lay down and sank into a not unpleasant, intoxicated-like condition characterized by an extremely stimulated imagination. In a dreamlike state, with eyes closed (I found the daylight to be unpleasantly glaring), I perceived an uninterrupted stream of fantastic pictures, extraordinary shapes with intense, kaleidoscopic play of colors. After some two hours this condition faded away."

After intentionally taking the drug again to confirm that it had caused this strange physical and mental state, Dr. Hoffman published a report announcing his discovery, and so LSD made its entry into the world as a hallucinogenic drug. Widespread use of the so-called "mind-expanding" drug did not begin until the 1960s, when counterculture figures such as Albert M. Hubbard, Timothy Leary, and Ken Kesey publicly expounded on the benefits of using LSD as a recreational drug. The manufacture, sale, possession, and use of LSD, known to cause negative reactions in some of those who take it, were made illegal in the United States in 1965.

On April 17, 1790, American statesman, printer, scientist, and writer Benjamin Franklin dies in Philadelphia at age 84.

Born in Boston in 1706, Franklin became at 12 years old an apprentice to his half brother James, a printer and publisher. He learned the printing trade and in 1723 went to Philadelphia to work after a dispute with his brother. After a sojourn in London, he started a printing and publishing press with a friend in 1728. In 1729, the company won a contract to publish Pennsylvania's paper currency and also began publishing the Pennsylvania Gazette, which was regarded as one of the better colonial newspapers. From 1732 to 1757, he wrote and published Poor Richard's Almanack, an instructive and humorous periodical in which Franklin coined such practical American proverbs as "God helps those who help themselves" and "Early to bed and early to rise, makes a man healthy, wealthy, and wise."

As his own wealth and prestige grew, Franklin took on greater civic responsibilities in Philadelphia and helped establish the city's first circulating library, police force, volunteer fire company, and an academy that became the University of Pennsylvania. From 1737 to 1753, he was postmaster of Philadelphia and during this time also served as a clerk of the Pennsylvania legislature. In 1753, he became deputy postmaster general, in charge of mail in all the northern colonies.

Deeply interested in science and technology, he invented the Franklin stove, which is still manufactured today, and bifocal eyeglasses, among other practical inventions. In 1748, he turned his printing business over to his partner so he would have more time for his experiments. The phenomenon of electricity fascinated him, and in a dramatic experiment he flew a kite in a thunderstorm to prove that lightning is an electrical discharge. He later invented the lightning rod. Many terms used in discussing electricity, including positive, negative, battery, and conductor, were coined by Franklin in his scientific papers. He was the first American scientist to be highly regarded in European scientific circles.

Franklin was active in colonial affairs and in 1754 proposed the union of the colonies, which was rejected by Britain. In 1757, he went to London to argue for the right to tax the massive estates of the Penn family in Pennsylvania, and in 1764 went again to ask for a new charter for Pennsylvania. He was in England when Parliament passed the Stamp Act, a taxation measure to raise revenues for a standing British army in America. His initial failure to actively oppose the controversial act drew wide criticism in the colonies, but he soon redeemed himself by stoutly defending American rights before the House of Commons. With tensions between the American colonies and Britain rising, he stayed on in London and served as agent for several colonies.

In 1775, he returned to America as the American Revolution approached and was a delegate at the Continental Congress. In 1776, he helped draft the Declaration of Independence and in July signed the final document. Ironically, Franklin's illegitimate son, William Franklin, whom Franklin and his wife had raised, had at the same time emerged as a leader of the Loyalists. In 1776, Congress sent Benjamin Franklin, one of the embattled United States' most prominent statesmen, to France as a diplomat. Warmly embraced, he succeeded in 1778 in securing two treaties that provided the Americans with significant military and economic aid. In 1781, with French help, the British were defeated. With John Jay and John Adams, Franklin then negotiated the Treaty of Paris with Britain, which was signed in 1783.

In 1785, Franklin returned to the United States. In his last great public service, he was a delegate to the Constitutional Convention of 1787 and worked hard for the document's ratification. After his death in 1790, Philadelphia gave him the largest funeral the city had ever seen.

In Massachusetts, British troops march out of Boston on a mission to confiscate the Patriot arsenal at Concord and to capture Patriot leaders Samuel Adams and John Hancock, known to be hiding at Lexington. As the British departed, Boston Patriots Paul Revere and William Dawes set out on horseback from the city to warn Adams and Hancock and rouse the Patriot minutemen.

By 1775, tensions between the American colonies and the British government approached the breaking point, especially in Massachusetts, where Patriot leaders formed a shadow revolutionary government and trained militias to prepare for armed conflict with the British troops occupying Boston. In the spring of 1775, General Thomas Gage, the British governor of Massachusetts, received instructions from England to seize all stores of weapons and gunpowder accessible to the American insurgents. On April 18, he ordered British troops to march against Concord and Lexington.

The Boston Patriots had been preparing for such a British military action for some time, and upon learning of the British plan Revere and Dawes set off across the Massachusetts countryside. Taking separate routes in case one of them were captured, Dawes left Boston by the Boston Neck peninsula, and Revere crossed the Charles River to Charlestown by boat. As the two couriers made their way, Patriots in Charlestown waited for a signal from Boston informing them of the British troop movement. As previously agreed, one lantern would be hung in the steeple of Boston's Old North Church, the highest point in the city, if the British were marching out of the city by Boston Neck, and two if they were crossing the Charles River to Cambridge. Two lanterns were hung, and the armed Patriots set out for Lexington and Concord accordingly. Along the way, Revere and Dawes roused hundreds of minutemen, who armed themselves and set out to oppose the British.

Revere arrived in Lexington shortly before Dawes, but together they warned Adams and Hancock and then set out for Concord. Along the way, they were joined by Samuel Prescott, a young Patriot who had been riding home after visiting a friend. Early in the morning of April 19, a British patrol captured Revere, and Dawes lost his horse, forcing him to walk back to Lexington on foot. However, Prescott escaped and rode on to Concord to warn the Patriots there. After being roughly questioned for an hour or two, Revere was released when the patrol heard minutemen alarm guns being fired on their approach to Lexington.

Around 5 a.m., 700 British troops under Major John Pitcairn arrived at the town to find a 77-man-strong colonial militia under Captain John Parker waiting for them on Lexington's common green. Pitcairn ordered the outnumbered Patriots to disperse, and after a moment's hesitation the Americans began to drift off the green. Suddenly, the "shot heard around the world" was fired from an undetermined gun, and a cloud of musket smoke soon covered the green. When the brief Battle of Lexington ended, eight Americans lay dead and 10 others were wounded. Only one British soldier was injured, but the American Revolution had begun.

At Mount Carmel in Waco, Texas, the Federal Bureau of Investigation (FBI) launches a tear-gas assault on the Branch Davidian compound, ending a tense 51-day standoff between the federal government and an armed religious cult. By the end of the day, the compound was burned to the ground, and some 80 Branch Davidians, including 22 children, had perished in the inferno.

On February 28, 1993, agents of the U.S. Treasury Department's Bureau of Alcohol, Tobacco and Firearms (ATF) launched a raid against the Branch Davidian compound as part of an investigation into illegal possession of firearms and explosives by the Christian cult. As the agents attempted to penetrate the complex, gunfire erupted, beginning an extended gun battle that left four ATF agents dead and 15 wounded. Six Branch Davidians were fatally wounded, and several more were injured, including David Koresh, the cult's founder and leader. After 45 minutes of shooting, the ATF agents withdrew, and a cease-fire was negotiated over the telephone. The operation, which involved more than 100 ATF agents, was one of the largest ever mounted by the bureau and resulted in the highest casualties of any ATF operation.

David Koresh was born Vernon Wayne Howell in Houston, Texas, in 1959. In 1981, he joined the Branch Davidians, a sect of the Seventh Day Adventist Church founded in 1934 by a Bulgarian immigrant named Victor Houteff. Koresh, who possessed an exhaustive knowledge of the Bible, rapidly rose in the hierarchy of the small religious community, eventually entering into a power struggle with the Davidians' leader, George Roden.

For a short time, Koresh retreated with his followers to eastern Texas, but in late 1987 he returned to Mount Carmel with seven armed followers and raided the compound, severely wounding Roden. Koresh went on trial for attempted murder, but the charge was dropped after his case was declared a mistrial. By 1990, he was the leader of the Branch Davidians and legally changed his name to David Koresh, with David representing his status as head of the biblical House of David, and Koresh standing for the Hebrew name for Cyrus, the Persian king who allowed the Jews held captive in Babylon to return to Israel.

Koresh took several wives at Mount Carmel and fathered at least 12 children from these women, several of whom were as young as 12 or 13 when they became pregnant. There is also evidence that Koresh may have harshly disciplined some of the 100 or so Branch Davidians living inside the compound, particularly his children. A central aspect of Koresh's religious teachings was his assertion that the apocalyptic events predicted in the Bible's book of Revelation were imminent, making it necessary, he asserted, for the Davidians to stockpile weapons and explosives in preparation.

Following the unsuccessful ATF raid, the Federal Bureau of Investigation (FBI) took over the situation. A standoff with the Branch Davidians stretched into seven weeks, and little progress was made in the telephone negotiations, as the Davidians had stockpiled years of food and other necessities before the raid.

On April 18, U.S. Attorney General Janet Reno approved a tear-gas assault on the compound, and at approximately 6:00 a.m. on April 19 the Branch Davidians were informed of the imminent attack and asked to surrender, which they refused to do. A few minutes later, two FBI combat vehicles began inserting gas into the building and were joined by Bradley tanks, which fired tear-gas canisters through the compound's windows. The Branch Davidians, many with gas masks on, refused to evacuate, and by 11:40 a.m. the last of some 100 tear-gas canisters was fired into the compound. Just after noon, a fire erupted at one or more locations on the compound, and minutes later nine Davidians fled the rapidly spreading blaze. Gunfire was reported but ceased as the compound was completely engulfed by the flames.

Koresh and at least 80 of his followers, including 22 children, died during the federal government's second disastrous assault on Mount Carmel. The FBI and the Justice Department maintained there was conclusive evidence that the Branch Davidian members ignited the fire, citing an eyewitness account and various forensic data. Of the gunfire reported during the fire, the government argued that the Davidians were either killing each other as part of a suicide pact or were killing dissenters who attempted to escape the Koresh-ordered suicide by fire. Most of the surviving Branch Davidians contested this official position, as do some critics in the press and elsewhere, whose charges against the ATF and FBI's handling of the Waco standoff ranged from incompetence to premeditated murder. In 1999, the FBI admitted they used tear-gas grenades in the assault, which have been known to cause fires because of their incendiary properties.

On this day in 1999, two teenage gunmen kill 13 people in a shooting spree at Columbine High School in Littleton, Colorado, south of Denver. At approximately 11:19 a.m., Dylan Klebold, 18, and Eric Harris, 17, dressed in trench coats, began shooting students outside the school before moving inside to continue their rampage. By 11:35 a.m., Klebold and Harris had killed 12 fellow students and a teacher and wounded another 23 people. Shortly after noon, the two teens turned their guns on themselves and committed suicide.

The crime was the worst school shooting in U.S. history (until 33 people, including the gunman, were killed in the Virginia Tech shooting on April 16, 2007) and prompted a national debate on gun control and school safety, as well as a major investigation to determine what motivated the teen gunmen. In the days immediately following the shootings, it was speculated that Klebold and Harris purposely chose jocks, minorities and Christians as their victims. It was initially reported that one student, Cassie Bernall, was allegedly asked by one of the gunmen if she believed in God. When Bernall said, "Yes," she was shot to death. Her parents later wrote a book titled "She Said Yes," honoring their martyred daughter. Apparently, however, the question was not actually posed to Bernall but to another student who had already been wounded by a gunshot. When that victim replied, "Yes," the shooter walked away. Subsequent investigations also determined that Harris and Klebold chose their victims randomly. Their original plan was for two propane bombs to explode in the school's cafeteria, potentially killing hundreds of people and forcing the survivors outside and into the gunmen's line of fire. When the bombs didn't work, Harris and Klebold went into the school to carry out their murderous rampage.

There was speculation that Harris and Klebold committed the killings because they were members of a group of social outcasts called the "Trenchcoat Mafia" that was fascinated by Goth culture. Violent video games and music were also blamed for influencing the killers. However, none of these theories was ever proven. Columbine High School reopened in the fall of 1999, but the massacre left a scar on the Littleton community. Mark Manes, the man who sold a gun to Harris and bought him 100 rounds of ammunition the day before the murders, was sentenced to six years in prison. In the aftermath of the Columbine shootings, many schools enacted "zero tolerance" rules regarding disruptive behavior and threats of violence from students.

According to tradition, on April 21, 753 B.C., Romulus and his twin brother, Remus, found Rome on the site where they were suckled by a she-wolf as orphaned infants. Actually, the Romulus and Remus myth originated sometime in the fourth century B.C., and the exact date of Rome's founding was set by the Roman scholar Marcus Terentius Varro in the first century B.C.

According to the legend, Romulus and Remus were the sons of Rhea Silvia, the daughter of King Numitor of Alba Longa. Alba Longa was a mythical city located in the Alban Hills southeast of what would become Rome. Before the birth of the twins, Numitor was deposed by his younger brother Amulius, who forced Rhea to become a vestal virgin so that she would not give birth to rival claimants to his title. However, Rhea was impregnated by the war god Mars and gave birth to Romulus and Remus. Amulius ordered the infants drowned in the Tiber, but they survived and washed ashore at the foot of the Palatine hill, where they were suckled by a she-wolf until they were found by the shepherd Faustulus.

Reared by Faustulus and his wife, the twins later became leaders of a band of young shepherd warriors. After learning their true identity, they attacked Alba Longa, killed the wicked Amulius, and restored their grandfather to the throne. The twins then decided to found a town on the site where they had been saved as infants. They soon became involved in a petty quarrel, however, and Remus was slain by his brother. Romulus then became ruler of the settlement, which was named "Rome" after him.

To populate his town, Romulus offered asylum to fugitives and exiles. Rome lacked women, however, so Romulus invited the neighboring Sabines to a festival and abducted their women. A war then ensued, but the Sabine women intervened to prevent the Sabine men from seizing Rome. A peace treaty was drawn up, and the communities merged under the joint rule of Romulus and the Sabine king, Titus Tatius. Tatius' early death, perhaps perpetrated by Romulus, left the Roman as the sole king again. After a long and successful rule, Romulus died under obscure circumstances. Many Romans believed he was changed into a god and worshipped him as the deity Quirinus. After Romulus, there were six more kings of Rome, the last three believed to be Etruscans. Around 509 B.C., the Roman republic was established.

Another Roman foundation legend, which has its origins in ancient Greece, tells of how the mythical Trojan Aeneas founded Lavinium and started a dynasty that would lead to the birth of Romulus and Remus several centuries later. In the Iliad, an epic Greek poem probably composed by Homer in the eighth century B.C., Aeneas was the only major Trojan hero to survive the Greek destruction of Troy. A passage told of how he and his descendants would rule the Trojans, but since there was no record of any such dynasty in Troy, Greek scholars proposed that Aeneas and his followers relocated.

In the fifth century B.C., a few Greek historians speculated that Aeneas settled at Rome, which was then still a small city-state. In the fourth century B.C., Rome began to expand within the Italian peninsula, and Romans, coming into greater contact with the Greeks, embraced the suggestion that Aeneas had a role in the foundation of their great city. In the first century B.C., the Roman poet Virgil developed the Aeneas myth in his epic poem the Aeneid, which told of Aeneas' journey to Rome. Augustus, the first Roman emperor and emperor during Virgil's time, and Julius Caesar, his great-uncle and predecessor as Roman ruler, were said to be descended from Aeneas.

Pat Tillman, who gave up his pro football career to enlist in the U.S. Army after the terrorist attacks of September 11, is killed by friendly fire while serving in Afghanistan on April 22, 2004. The news that Tillman, age 27, was mistakenly gunned down by his fellow Rangers, rather than enemy forces, was initially covered up by the U.S. military.

Patrick Daniel Tillman was born the oldest of three brothers on November 6, 1976, in San Jose, California. He played linebacker for Arizona State University, where during his senior year he was named Pac-10 Defensive Player of the Year. In 1998, Tillman was drafted by the Arizona Cardinals. He became the team’s starting safety as well as one of its most popular players. In 2000, he broke the team record for tackles with 224. In May 2002, Tillman turned down a three-year, multi-million-dollar deal with the Cardinals and instead, prompted by the events of 9/11, joined the Army along with his brother Kevin, a minor-league baseball player. The Tillman brothers were assigned to the 75th Ranger Regiment in Fort Lewis, Washington, and did tours in Iraq in 2003, followed by Afghanistan the next year.

On April 22, 2004, Pat Tillman was killed by gunfire while on patrol in a rugged area of eastern Afghanistan. The Army initially maintained that Tillman and his unit were ambushed by enemy forces. Tillman was praised as a national hero, awarded the Silver Star and Purple Heart medals and posthumously promoted to corporal. Weeks later, Tillman’s family learned his death had been accidental. His parents publicly criticized the Army, saying they had been intentionally deceived by military officials who wanted to use their son as a patriotic poster boy. They believed their son’s death was initially covered up by military officials because it could’ve undermined support for the wars in Iraq and Afghanistan.

A criminal investigation was eventually launched into the case and in 2007 the Army censured retired three-star general Philip Kensinger, who was in charge of special operations at the time of Tillman’s death, for lying to investigators and making other mistakes. “Memorandums of concern” were also sent to several brigadier generals and lower-ranking officers who the Army believed acted improperly in the case.

According to tradition, the great English dramatist and poet William Shakespeare is born in Stratford-on-Avon on April 23, 1564. It is impossible to be certain the exact day on which he was born, but church records show that he was baptized on April 26, and three days was a customary amount of time to wait before baptizing a newborn. Shakespeare's date of death is conclusively known, however: it was April 23, 1616. He was 52 years old and had retired to Stratford three years before.

Although few plays have been performed or analyzed as extensively as the 38 plays ascribed to William Shakespeare, there are few surviving details about the playwright's life. This dearth of biographical information is due primarily to his station in life; he was not a noble, but the son of John Shakespeare, a leather trader and the town bailiff. The events of William Shakespeare's early life can only be gleaned from official records, such as baptism and marriage records.

He probably attended the grammar school in Stratford, where he would have studied Latin and read classical literature. He did not go to university but at age 18 married Anne Hathaway, who was eight years his senior and pregnant at the time of the marriage. Their first daughter, Susanna, was born six months later, and in 1585 William and Anne had twins, Hamnet and Judith. Hamnet, Shakespeare's only son, died 11 years later, and Anne Shakespeare outlived her husband, dying in 1623. Nothing is known of the period between the birth of the twins and Shakespeare's emergence as a playwright in London in the early 1590s, but unfounded stories have him stealing deer, joining a group of traveling players, becoming a schoolteacher, or serving as a soldier in the Low Countries.

The first reference to Shakespeare as a London playwright came in 1592, when a fellow dramatist, Robert Greene, wrote derogatorily of him on his deathbed. It is believed that Shakespeare had written the three parts of Henry VI by that point. In 1593, Venus and Adonis was Shakespeare's first published poem, and he dedicated it to the young Henry Wriothesley, the 3rd earl of Southampton. In 1594, having probably composed, among other plays, Richard III, The Comedy of Errors, and The Taming of the Shrew, he became an actor and playwright for the Lord Chamberlain's Men, which became the King's Men after James I's ascension in 1603. The company grew into England's finest, in no small part because of Shakespeare, who was its principal dramatist. It also had the finest actor of the day, Richard Burbage, and the best theater, the Globe, which was located on the Thames' south bank. Shakespeare stayed with the King's Men until his retirement and often acted in small parts.

By 1596, the company had performed the classic Shakespeare plays Romeo and Juliet, Richard II, and A Midsummer Night's Dream. That year, John Shakespeare was granted a coat of arms, a testament to his son's growing wealth and fame. In 1597, William Shakespeare bought a large house in Stratford. In 1599, after producing his great historical series, the first and second part of Henry IV and Henry V, he became a partner in the ownership of the Globe Theatre.

The beginning of the 17th century saw the performance of the first of his great tragedies, Hamlet. The next play, The Merry Wives of Windsor, was written at the request of Queen Elizabeth I, who wanted to see another play that included the popular character Falstaff. During the next decade, Shakespeare produced such masterpieces as Othello, King Lear, Macbeth, and The Tempest. In 1609, his sonnets, probably written during the 1590s, were published. The 154 sonnets are marked by the recurring themes of the mutability of beauty and the transcendent power of love and art.

Shakespeare died in Stratford-on-Avon on April 23, 1616. Today, nearly 400 years later, his plays are performed and read more often and in more nations than ever before. In a million words written over 20 years, he captured the full range of human emotions and conflicts with a precision that remains sharp today. As his great contemporary the poet and dramatist Ben Jonson said, "He was not of an age, but for all time."

Colin Ross is hanged to death in Australia for the rape and murder of 13-year-old Alma Tirtschke. Ross was one of the first criminals in Australia to be convicted based on forensic evidence. On December 30, 1921, Tirtschke was reported missing in Melbourne. The next day, a constable patrolling Gun Alley, a well-known area for prostitutes, found the young schoolgirl's body bundled up in a blanket. Strangely, despite evidence of a brutal rape, there was no trace of blood found on her body.

Given the scarcity of cars in Melbourne at the time, the police surmised that the perpetrator had to live nearby. Prostitutes' eyewitness accounts led authorities to Colin Ross, who owned a nearby bar. Pretending to be helpful, Ross volunteered that Tirtschke had been at the bar on the day she was killed.

Police soon learned that Ross had previously indicated a predilection for young girls. He had reportedly told someone, "I prefer them without feathers." Although this was enough to convince law enforcement officials of Ross' guilt, additional evidence would be needed for a conviction. Since no evidence would be forthcoming from the obviously cleaned body, police turned their attention to Ross' house.

There they found a blanket that had long red hairs on it. The color and length matched Tirtschke's hair, and new experts in the field identified it as human. Some of the hairs had been pulled out at the roots, suggesting a struggle. At the trial, the defense challenged the forensics expert to distinguish and identify several hair samples. The strategy backfired when the expert did just that, and Ross was convicted. It is now believed, however, that Ross was almost certainly innocent. Recent forensic research has demonstrated that the hair samples were misidentified, either accidentally or at the behest of the police investigator in charge of the case.

On this day in 1983, the Soviet Union releases a letter that Russian leader Yuri Andropov wrote to Samantha Smith, an American fifth-grader from Manchester, Maine, inviting her to visit his country. Andropov's letter came in response to a note Smith had sent him in December 1982, asking if the Soviets were planning to start a nuclear war. At the time, the United States and Soviet Union were Cold War enemies.

President Ronald Reagan, a passionate anti-communist, had dubbed the Soviet Union the "evil empire" and called for massive increases in U.S. defense spending to meet the perceived Soviet threat. In his public relations duel with Reagan, known as the "Great Communicator," Andropov, who had succeeded longtime Soviet leader Leonid Brezhnev in 1982, assumed a folksy, almost grandfatherly approach that was incongruous with the negative image most Americans had of the Soviets.

Andropov's letter said that Russian people wanted to "live in peace, to trade and cooperate with all our neighbors on the globe, no matter how close or far away they are, and, certainly, with such a great country as the United States of America." In response to Smith's question about whether the Soviet Union wished to prevent nuclear war, Andropov declared, "Yes, Samantha, we in the Soviet Union are endeavoring and doing everything so that there will be no war between our two countries, so that there will be no war at all on earth." Andropov also complimented Smith, comparing her to the spunky character Becky Thatcher from "The Adventures of Tom Sawyer" by Mark Twain.

Smith, born June 29, 1972, accepted Andropov's invitation and flew to the Soviet Union with her parents for a visit. Afterward, she became an international celebrity and peace ambassador, making speeches, writing a book and even landing a role on an American television series. In February 1984, Yuri Andropov died from kidney failure and was succeeded by Konstantin Chernenko. The following year, in August 1985, Samantha Smith died tragically in a plane crash at age 13.
